To whom it may concern;

Be it known that I; Isrn B n ject of the Czar ofRussia, and a residentofthe city of New York, borough oi Brooklyn, in the county of Kings andvState of New York, have im ented a newpnd Improved Scale, ofwhichthe'following is a full, clear and exactdescription.

My invention relates "generally to'scales and more particularlycomprehends a new and impr d scale 'headiconstruction', the device beingadaptedfjior use wit-lrplatform scales of-idifferent makes. y

The principal object f n nventlon is'to; provide I n w, 1 and-.nnpi'oved scale hea made up are 'pluralr ovmg partsv whichja'lsectoriis act he r a exited on a suitable'scal'e thereby' 'ev the loadon the platforinfof the scales A further, object .oii-iny t inventioprovide a scaleheadrnadegup'ioff aiplui lity of parts cooperating witheach othenqthe said head, however; beingadapted-jformoth fieation' inthat" 'one -halfjpfj the said; head y; may be .used .jrvith smallplatform r scales whereas the headQaS an entirety, or} when constructed"of the plurality 'of simplelpa'rts,

is more particularly for use with platforms sustaining heavy loads.

A further object of the invention "is to] provide ascale head havingallover ofsuit-j able constructionmovably mounted at one end, thedeveribeing adapted to. be actuated by the movement of the platform so thatthe load carried on the platform willmove the lever, the point aboutwhich the lever swings being fixeth I a i A further object of theinvention is to provide a scale head havinga plurality of movable leversadapted to be simultaneously actuated by a platform so that the leverswill move together when a load is' applied to the platform, the pointsabout which the levers'siiingheing fixed;" I

A furthergohject jof Invention to provide aneiv andimprovedmeansforr'mov ing a pointer over a suitable dial -fthe said means beingactuatedby;thev movement of the lever in the scale headr teference is tobe had t the accompanying drawings forming apart of this specification,in which similar characters of reference denote corresponding parts inally the views and in which-- Figure 1 is a front view of the scalehead;

' Specification of Letters Patent.

CHARIi'r, a'sub-' n v1evv of Fig. 1; Fig. at 15 a view similar to meansof a cross piece/ta ind ' "'intheupper faces these bearings formingPatented (W. 11, 912i Fig. 2 is a vertical sectional view thereofon theline 22 of Fig. 3; F 1g. 3 IS a right end Fig. 2 but showing one-half ofthe head adapted for use with certain platforms.

Referring partlcularly to Figs. 1 to 3 inelusive, the scale headcomprises a fixed support made up of the base 1 having an open-f n'g 2tlfere1n, there being suitable standards or uprights 3 carried by thebase and post tioned adjacent the front and rear thereof,

each pair of uprights being preferably 'connected together at theirupper portions by fltesting on top of each pairof uprights is a support,5 having bearings fi tli creon, there being suitable members carriedby-u 'e ings and provided with v -sh'ape d recesses 7 rests forjpivotally mounting'the swing ng levers I 8 in position.

I *l atljrlever 8 comprises a niajor portion 9 having-a mass ofsultablefmaterial l0jf'ad ustably secured at v the f outer end thiereofy the lever also compr sing a minor portion! inthenatureiof an.oflset arm 11,' the outer end thereof being provided withav transverselyextnding'element 12 at "the opposite endsgofwhich are knife-edges 13,the our knife-edges engaging at the bottom of the l-shaped recesses 7 inthe bearings 6. Each mass of material 10 which 'is prefe'rably the: formof a ballis secured in position on .the portions 9 of the lever by meansof a set screvv 1 T he upper end of eachof the major 'p'ortions 9 oneach side is provided with lugs'lfi which are preferably wedge-shape inCross section, such a con-.. struction providing for knife-edge supportswith suitable hooks 16 having openings 17 therein, the side \vallof theopenings resting on the sai'tl'icnife edges. The lower end of each hookis provided with a'bent portion 18 the suspending lever 19 being inengagement with each of these bent portions 13 through the medium of atransversely extending bar 20 having upstanding parts 21 From what hasbeen said it will be ob-' vious that if the suspending lever 19 isengaged with a platform of a scale which is will move the hooks 16 down,the levers 8- *ters;

properly mounted in a suitable pitthat downward movement of thissuspending lever when a load is applied to the platform justed that theoutward movement of .the

levers will vary when the same loadis ap-' plied to the scales,therebyproviding for the same scale head being used with scalesforweighing loads over difierent ranges.'

In or r that'the outward movementpf either lever B, which movementdepends on the load may be properlyindicated I; have provide a dial witha pointersgplaying l thereover in order that-,the-load,niaygbe ablycomprises announced. This indicating devicegpreferstandin frame 32;which'i s mounted on the scale head in any portion of the sector isprovidedwith Zl'ack 33 which engages a p1mon.3 &,mounted}ona the frontend ofthe spindle bespindle 35, Y ing provided with apointez-Bflwhichmoves around a preferably circular dial 37,;Movement ofthe levers-8 istransmittedto the pointer 36 by means oftheconnectingbar' w 38, preferably integral-with .the.sector,,the

. standing connecting intermediate portion .39. being preferably offsetin order to provide ,forcompact-sar u De e offlm;

rangement of the parts, the bar being provided with kni e edges 40resting in suitable supports notches therein; these supports rarelpreferably carried by the before-mentioned upframe 32. Y The upper endof this sector 30 although itfis obvious that they may bemade separatelyand suitabl 'connected to ether. The lower end of .t e bar 38 is preerably bifurcated and .is provided pin engages ,in'the arcuate slot 44carried by a fixed element 45 which issecured to thc side of-one of thelevers 8. i

It will be obvious that as the sus ending lever 19 is moved downwardl tlat the levers 8 will swing about the lmi ports 13 as centers, theweights 10 thereby movingaway from each other, the pin and slotengagement with the parts 33, 34, caus-' 7 ing the-connecting bar 38 tomove aboutthe knife edge supports 40, 41, as centers, thereby turningthe sector or quadrant 30 and with it the spindle 34, tne angular travelof thespindle moving the pointer over the dial 37.

It is to be noted that each oi the sup ports-about wh ch he lovers 8move is fixed of the suspending lever the position of these masses onThe weights 10 may be so ada ct r 30 wh h is i o ably carried bet-weenopposite s des of the np-I suitable position the edge z 41 hav n gsh pir bar is shownintegralwith the.

e ed e sup and that the weights 10 are'olso fixed with respect to thelevers so that the same travel 19 will always cause either lever 8 tomove through the same angle. 7 I

' Referring particularly to Figs; 1 and 2 it. will be noted that t eprovision of the sector 30 and the inion34 provides for utilizing all ofthe ial 37, it being clear that the numerals placed thereon may be suchas are fitted to the'size of the scales, which means that the weights 1(may occupy different positions in scales registering differentmaximumamounts when these scales are provided with'the same scale heads. a Itwill also benoted that by reasonof thesmall number of contacts of thevarious moving parts that the friction is materially reduced,

the balance of. the scale head being substantially 1 identicalafter;each Wcigh1ng' by thescale.

,One feature of the. scale head herein described and illustrated is thatthe construction thereof permits the use of one half of thehead in thecaseof small scales andin Fig; .i such a scale is illustrated j In this"scale the depai ture froin what is shown in Figs} 1 to 3lies pending rodl9 .'is secured at its upper "end in the'fact that. the 'susdirectly tothe bent' end l 8 of the book 16, the opening 1'41 in the upper end ofthe hook engagingtheiknife edge or 'ivedge-sliape'support 15 at theupper end of the lever 8;} As the scalejhead her shown is substantiallytone-half of that'previously described," it is believed that theoperation thereof will be clearly understood fromwhat has beenpreviously said, the parts used beingidentical,

with tlie exception noted, to whathas' gone before.

.'In conclusion it is to be noted that the scale head herein shown ismade up offew parts; the partsare articl'llated in such a way, by reason oftheknife edge supports, as to structure and number that the friction isreduced to a minimum and a I nore perfect balance is obtained, thesefeaturesften'ding to the production of a scale head fofierin manyadvantages and overcoming many 0% the defects present in devicesnow'iised for the same purpose.
